Abstract
It the utility model is related to a kind of transition apparatus for thin-wall pipe spot welding, including stent, spring leaf and chromium-zirconium-copper rebound；Cradle top connecting spring piece, chromium-zirconium-copper rebound is installed on spring leaf.The rebound of chromium-zirconium-copper material has good electric conductivity and certain intensity, during welding, chromium-zirconium-copper rebound is acted between bottom electrode and jointed tubular workpieces to be welded, forms transitional function, reduces burn-through or risk that weldering is split；Increased floating spring piece can play the role of preferable flexibility, the upward lifting process of robot soldering pliers bottom electrode is had flexibility, play the role of good hold out against.Simple in structure, Product jointing effect is good, and yield rate is improved.
Description
Technical field
The utility model relates generally to the field of spot welding device, and more particularly to a kind of transition for thin-wall pipe spot welding fills
Put.
Background technology
The prior art is directly acted on thin-wall pipe with robot bottom electrode, and top electrode applies certain pressure, passes through
Larger current, so that weld-end fittings, but because wall thickness is relatively thin, it is most likely that cause thin-walled breakdown or crackle, cause product unqualified.
Utility model content
The utility model is in view of the above-mentioned problems, provide a kind of transition apparatus for thin-wall pipe spot welding.
The purpose of this utility model can be realized by following technical proposals：A kind of transition for thin-wall pipe spot welding
Device, including stent, spring leaf and chromium-zirconium-copper rebound；The stent is L-shaped and erects setting, the top fixed spring of stent
Piece, spring leaf are connected as a single entity are formed successively by vertical portion, rake and horizontal part three parts, vertical portion, rake and horizontal part
To set gradually from bottom to up, vertical portion is vertically arranged and is connected with the top of stent, and rake is obliquely installed, under rake
End is connected with vertical portion, and the upper end of rake is connected with horizontal part, and horizontal part is horizontally disposed with, and chromium-zirconium-copper transition is installed on horizontal part
Plate, offers hole on the horizontal part of spring leaf.
Further, the robot soldering pliers top electrode arranged up and down and robot soldering pliers bottom electrode, the spring are further included
The horizontal part and chromium-zirconium-copper rebound of piece are between robot soldering pliers top electrode and robot soldering pliers bottom electrode.
The beneficial effects of the utility model：The rebound of chromium-zirconium-copper material has good electric conductivity and certain intensity,
Chromium-zirconium-copper rebound is acted between bottom electrode and jointed tubular workpieces to be welded, forms transitional function, the forced area of thin-wall pipe（It is logical
Electric area）Increase, it is possible to reduce burn-through or weld the risk split；Increased floating spring piece can play preferable flexible work
With, make the upward lifting process of robot soldering pliers bottom electrode have flexibility, play the role of good hold out against.It is simple in structure, product weldering
It is good to connect effect, yield rate is improved.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model concrete application.
Fig. 2 is the structure diagram of the utility model.
Part numbers are as follows in figure：
1 stent, 2 spring leafs, 21 vertical portions, 22 rakes, 23 horizontal parts, 3 chromium-zirconium-copper rebounds, on 4 robot soldering pliers
Electrode, 5 robot soldering pliers bottom electrodes, 6 pipe fittings.
Embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing, becomes apparent from those skilled in the art
Ground understands how to put into practice the utility model.Although describing the utility model with reference to its preferred embodiment, these
Embodiment simply illustrates, rather than limitation the scope of the utility model.
Robot soldering pliers top electrode 4 and robot soldering pliers bottom electrode 5 are in the thin-wall hollow pipe that spot welding wall thickness is less than 2mm
Part, easily leads to thin-walled breakdown or crackle.To avoid such case, as depicted in figs. 1 and 2, the utility model one kind is used for thin-walled
The transition apparatus of pipe fitting spot welding, including stent 1, spring leaf 2 and chromium-zirconium-copper rebound 3；The stent 1 is L-shaped and erects setting,
The top stationary spring 2 of stent 1, spring leaf 2 are connected as a single entity successively by vertical portion 21, rake 22 and 23 three parts of horizontal part
Form, vertical portion 21, rake 22 and horizontal part 23 to set gradually from bottom to up, vertical portion 21 be vertically arranged and with stent 1
Top connection, rake 22 is obliquely installed, and the lower end of rake 22 is connected with vertical portion 21, upper end and the level of rake 22
Portion 23 connects, and horizontal part 23 is horizontally disposed, and chromium-zirconium-copper rebound 3 is installed on horizontal part 23, is opened up on the horizontal part 23 of spring leaf 2
It is useful for the hole that robot soldering pliers bottom electrode 5 is contacted with chromium-zirconium-copper rebound 3.
The material chromium-zirconium-copper of chromium-zirconium-copper rebound 3 has good electric conductivity, and thermal conductivity, hardness is high, wear-resisting antiknock, crack resistance
And softening temperature is high, export license is few during welding, and speed of welding is fast, and welding assembly sheet is low, is suitable as the electricity of welding welding machine
Extremely in relation to pipe fitting.
Before spot welding, and treat that the pipe fitting 6 of spot welding can be held up by fulcrum bearing and make somebody a mere figurehead, the position of the utility model transition apparatus is consolidated
It is fixed, the horizontal part 23 of spring leaf 2 and chromium-zirconium-copper rebound 3 be located at below pipe fitting 6, during spot welding, robot soldering pliers bottom electrode 5
In the lower section of pipe fitting 6,5 uplink of robot soldering pliers bottom electrode directly acts on chromium-zirconium-copper by the hole on 2 horizontal part 23 of spring leaf
On rebound 3, top downlink of the robot soldering pliers top electrode 4 from pipe fitting 6, you can be engaged and spot welding is carried out to pipe fitting 6.Due to chromium
The transitional function of zirconium copper rebound 3, the forced area of thin-wall pipe 6（Energization area）Increase, it is possible to reduce burn-through or weldering is split
Risk；Increased floating spring piece 2 can play the role of preferable flexibility, make the 5 upward lifting of robot soldering pliers bottom electrode
Journey tool is flexible, plays the role of good hold out against.
It should be pointed out that for the utility model through absolutely proving, can also have a variety of conversion and the implementation of remodeling
Scheme, it is not limited to the specific embodiment of the above embodiment.Above-described embodiment as just the utility model explanation, and
It is not the limitation to the utility model.In short, the scope of protection of the utility model should include those for ordinary skill
Obviously convert or substitute and retrofit for personnel.
